GroupLayout未按预期运行
GroupLayout未按预期运行
提问于 2013-02-06 22:08:29
我试图创建一个扫雷舰类型的游戏，并已围绕在顶部的GridLayout和底部的JPanel设计了界面。我在底部的信息面板上排列JComponents时遇到了问题。我正在使用GroupLayout来排列信息面板中的项目。
下面是它应该如何显示的基本图形：
这是实际的结果：
我不明白为什么最底层的标签(大的是playerXTurnIndicator标签)根本没有显示出来。默认情况下，当它们被添加到没有文本的组中时，它们肯定会采用水平或垂直布局指定的区域大小？
private void createComponents() {
playerOneNameLabel = new JLabel("Name : ");
playerTwoNameLabel = new JLabel("Name : ");
playerOneScoreLabel = new JLabel("Score : ");
playerTwoScoreLabel = new JLabel("Score : ");
playerOneNameDataLabel = new JLabel("");
playerTwoNameDataLabel = new JLabel("");
playerOneScoreDataLabel = new JLabel("0");
playerTwoScoreDataLabel = new JLabel("0");
playerOneTurnIndicatorLabel = new JLabel();
playerOneTurnIndicatorLabel.setBackground(Color.GREEN);
playerOneTurnIndicatorLabel.setPreferredSize(new Dimension(100, 20));
playerTwoTurnIndicatorLabel = new JLabel();
playerTwoTurnIndicatorLabel.setBackground(Color.RED);
playerTwoTurnIndicatorLabel.setPreferredSize(new Dimension(100, 20));
infoMinesRemainingLabel = new JLabel("Mines Remaining : ");
infoMinesRemainingData = new JLabel("0");
infoTileCoordLabel = new JLabel("Tile : ");
infoTileCoordDataLabel = new JLabel("0, 0");
playerOneBombButton = new JButton("Bomb");
playerTwoBombButton = new JButton("Bomb");
GroupLayout layout = new GroupLayout(this);
layout.setAutoCreateContainerGaps(true);
layout.setAutoCreateGaps(true);
layout.setHorizontalGroup(
layout.createSequentialGroup()
.addGroup(
layout.createSequentialGroup()
.addGroup(
layout.createParallelGroup()
.addGroup(
layout.createSequentialGroup()
.addComponent(playerOneNameLabel)
.addComponent(playerOneNameDataLabel))

layout.createSequentialGroup()
.addComponent(playerOneScoreLabel)
.addComponent(playerOneScoreDataLabel))
.addComponent(playerOneTurnIndicatorLabel))
.addComponent(playerOneBombButton))
.addGap(10)

.addComponent(playerTwoNameLabel)
.addComponent(playerTwoNameDataLabel))
.addGroup(
layout.createSequentialGroup()
.addComponent(playerTwoScoreLabel)
.addComponent(playerTwoScoreDataLabel))
.addComponent(playerTwoTurnIndicatorLabel))));
layout.setVerticalGroup(
layout.createParallelGroup()
.addGroup(

)
.addGap(50)

.addComponent(playerTwoTurnIndicatorLabel))));
this.setLayout(layout);
}致以敬意，

显示了JLabels (因此底部的可用空间)，但没有颜色。请改用JPanels (背景仅适用于不透明组件，请参见http://docs.oracle.com/javase/7/docs/api/javax/swing/JComponent.html#setBackground%28java.awt.Color%29)。
